[Underware-devel] OpenSceneGraph in pong

[Loic Dachary]

        Hi,

        I've replaced raw OpenGL calls with OpenSceneGraph calls in
pong. The scene is built by the program rather than loaded from a
file. You will find the modified underware distribution at
http://www.dachary.org/underware/underware-0.1.4.tar.gz

        Although not documented OpenSceneGraph is usable. I avoided
the high level facilities that do not really belong to a scene graph
(Producer & al). The class information HTML pages provided with the
distribution are hardly usable and I generated a doxygen equivalent
that is available at 
http://www.mekensleep.com/underware/openscenegraph/html/html/index.html

        I guess we will have many discussions related to the choice of
OpenSceneGraph. My impression is that the burden of using a rather
complex and non documented library is outweighted, in this specific
case, by the services it provides. I don't see any reason why
OpenSceneGraph should become a burden or a showstopper. It has been
designed for performances which is a must. It also evolved with the
ambition of becoming a general purpose library focused on a single
topic. If we were to use the scene graph of a more ambitious library
such as NeL, crystalspace or ogre, it would be less mature and very
hard to separate from the functionalities unrelated to a scene graph.

        Here is the updated list of the dependencies of underware,
as published at http://www.mekensleep.com/underware/.
